I have a friend that has a 97 RR and the heat stopped working. Fan works, doesn't overheat just blows cold air. Thanks.

 

Blend motors are probably frozen. If you cycle from HI to LO on the temps, you can sometimes free them.

 

LR Scott,
Nice new picture of your RR. Looks like it busting through mounds of snow!

 

Its actually stuck in the picture... lol The plows come through our neighborhood and leave these piles of snow all over the place. I can usually be seen in the morning blasting through them with the grill guard. SO MUCH FUN! No damage or anything to the rig, but snow blows up everywhere. Well there was a particular mound a bit bigger than normal. Rammed it and the axle in the front axle got buried and the rear tires were on a bunch ice.... Took about 10 min to get it out. Fun times!

 

At least the plow did not move a massive ice clump in the pile you went through, that would have made the stuck a little more painful.

 

Blend door motors and/or the heater box may be warped, pull the blend door, upper on right side next to srs airbag, and work door by hand, should have little resistance, if not or if it has a tight spot you may need the whole sha-bang!

 

It could be as simple as a clogged heater core.

 

I have been wondering about my blend motors. My Rover does go from hot to cold but it never seems to get as hot or as cold as my other vehicles.

 

So, when was the last time you checked/added coolant? You have a leaker and had better deal with it before you loose a head gasket.

 

Kinda dealing with the same issue with my 95 LWB as KRAZZ describes. I want to chalk it up to it being 10F or lower, but it seems that the heat should be better than luke warm. I've looked for wetness around the heater core, coolant level is solid and unwavering.
There is a strange gurgling at times behind the dash at times, leading me to fear heater core, but I have found nothing to indicate an issue there. I'll try the hot to cold to hot trick tomorrow morning, then look deeper.
